Most of my houses are bank owned. I actually just bought a foundation from a builder that went under for 20K. Foundation alone is worth 17K, I'll have about 100 into the whole project when it is done and the house should sell easily for about 155K.
I also bought a foreclosure to use as a rental. Purchase = 50K, 10K Rehab, Refi at $75K, pull 15K out for capital and rent the house out. Mortgage/tax/insurance $660, rent $900 so making $240 a month plus pulling out $15K.
Then on the same day I bought a house on short sale for 75K, assessed at 150, rehab =20K, sell at 129,900.
Things aren't as bad as they seem.
